So it''s possible that, if same kernel works well natively, those Xen stubs are out of sync with original version. This is not a clean approach, and we need consider a better one for pushing them upstream. :/ Thanks Kevin _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
